From shafting and supports, to round and square rail guides, linear motion systems to pillow blocks, Thomson demonstrates how our products excel as the best solution in a wide array of industrial applications.

Electrak 2 Linear Actuators

The Electrak® 2 linear actuator is an economical model designed for relatively light load applications. It incorporates most of the features found in higher priced models, but utilizes a heavy duty acme screw drive system. The Acme screw is self-locking and therefore does not need a brake to prevent backdriving the load. A built in overload clutch slips when the factory-set load limit is exceeded.

Stroke Length

This value is the maximum extension of the actuator system itself. Your max application length should be within the selected range. Each system, however, can be ordered in shorter standard or customizable lengths.

Dynamic Load

The dynamic load rating is how much load the actuator will move when power is applied.

Travel Rate

DC actuators have a direct load/speed relationship. As the load increases, the speed of the dc actuators decreases. There are curves on each product page to show the speed from no load to full rated load. AC actuators have very little speed fluctuations based on load but there are load/speed curves on all the ac actuator product pages

Motor Voltage

The nominal voltage required to operate the actuator. All actuators will accept at least a ± 10 % variation of the nominal voltage but a change in the voltage will result in a change of the speed of dc actuators. Controls are available that accept 115 or 230 Vac input and provide 24 Vdc output to operate 24 Vdc actuators.

Screw Type

Actuators use three different types of screws depending on the configuration and load requirements of the actuator. Ball screws are highly efficient and are used for high loads and speeds. Acme screws withstand vibration and shock better and are used for applications with these characteristics. Worm screws are self locking and will not backdrive.
